PURPOSE OF THE STUDY: Intraarticular fractures of the distal femur rank among the most severe musculoskeletal injuries. Various treatment options, such as plate osteosynthesis or retrograde nailing, can be employed. This study aims to evaluate the clinical outcomes and complications of intraarticular distal femoral fractures treated with retrograde femoral nail, with particular emphasis on C3 fractures. MATERIAL AND METHODS: Between January 2016 and January 2023, 18 AO/33.C3 fractures were treated with a retrograde femoral nail. Of these, two were classified as 33.C1, eight as 33.C2 and eight as 33.C3. Twelve of the fractures were open. After the initial treatment and stabilizing the patient's overall condition, we proceeded with the definitive osteosynthesis. The first phase involved open reduction and fixation using individual screws to reconstruct the articular surface. The second phase consisted in retrograde nailing with correction of the length, axis and rotation of the femur. The evaluation criteria included: complication rate, number of revisions, knee range of motion, mechanical axis and length of the lower extremity, progression of gonarthrosis, pain level, need of walking support, Lysholm and Tegner Activity Score for functional outcome. RESULTS: Overall, we evaluated the complications and the outcomes of 12 patients (13 fractures). Of these, 8 patients experienced some kind of postoperative complications, primarily insufficient healing or nonunion, which were managed through revision surgery. Plate reosteosynthesis was used in 2 patients who were then excluded from the final clinical evaluation. No cases of deep infection or deep vein thrombosis were reported and no patient required total knee replacement. Seven AO/33.C3 fractures were individually evaluated. The average knee range of motion was nearly 0-93°, maximum flexion was 120°. On average, the lower extremity was 1.6 cm shorter and 7.3° varus to the mechanical axis. Only little progression of gonarthrosis was observed along with low levels of pain. The Lysholm Score ranged between 52 and 84 points (averaging 73.1). The mean Tegner Activity Score was 3.4. All results showed adequate improvement in 33.C2 and 33.C1 groups. DISCUSSION: The retrograde femoral nail demonstrates several advantages over the locking compression plate, particularly in biomechanical aspects. Various clinical studies have reported superior outcomes in terms of healing, complication rate, blood loss and functional outcome. Our study findings align with some of those international studies, particularly in the rate of infectious complications (0%), mean Lysholm Score (79.3 p.) and Tegner Activity Score (4.1). On the other hand, we observed a higher rate of revision surgery (53.8 %), mainly due to evaluating 33.C fractures only. The main advantage of this method lies in complete visualization, leading to better reconstruction of the articular surface coupled with excellent biomechanical properties of the intramedullary nail. CONCLUSIONS: Intraarticular distal femoral fractures pose significant challenges to treatment and frequently lead to permanent damage. The primary treatment goals involve achieving anatomical reposition of the articular surface, stable osteosynthesis, correction of the femoral length and axis and early rehabilitation. Our study demonstrates good clinical outcomes with a relatively low rate of complications. Patients are capable of walking without pain, achieving a good range of motion, returning to their occupations and becoming self-sufficient. Moreover, there were no infectious complications and no significant progression of gonarthrosis. KEY WORDS: retrograde femoral nail, intraarticular distal femoral fracture, functional outcome, complication rate.

PURPOSE OF THE STUDY It was a prospective, randomised, unblinded study. Effects of the application of platelet-rich fibrin (PRF) on the anatomic anterior ligament reconstruction were examined. MATERIAL AND METHODS A total of 40 patients who underwent a surgery between 2012 and 2014 were enrolled in the study. The patients were randomised into two groups: the group with PRF application (n=20) and the group without PRF application (n=20, control group). The study included 11 women and 29 men, with the mean age at the time of inclusion into the study 29.1 years. Vivostat ® PRF was obtained perioperatively from the patient s blood and applied intraoperatively to the hamstring tendon graft. The ACL graft healing was assessed through magnetic resonance (MRI) at 6 and 12 months postoperatively. The clinical outcomes (the Lysholm score and the IKDC Subjective score, return to pre-injury sport levels, Pivot-shift test, graft failure) as well as standardised laxity measurements using GenouRob arthrometer were performed preoperatively and 12 months after surgery. RESULTS The study was completed by thirty-three (33) patients (17 in the PRF group and 16 in the control group). In two cases, postoperative graft failure was reported (both cases in the control group). No significant differences were found in the process of graft ligamentization evaluated through MRI (p=0.07). No significant difference between the groups was identified with respect to return to pre-injury sport levels (p=0.232), or the Lysholm score and IKDC Subjective score (p=0.259, and p=0.364 respectively). The postoperative knee laxity measurement using Genourob arthrometer did not reveal any significant differences between the PRF group and the control group. DISCUSSION Results similar to those arrived at by our study have recently been published also by other authors worldwide. We can therefore assume that the application of PRF can be of benefit, especially at the early stage of healing. The results still need to be verified on a larger study group, the study design should focus on the development in the early postoperative period. CONCLUSIONS In our study group, no significant difference was observed in the evaluated subjective and objective clinical parameters. Only the parameter regarding the ACL graft failure fell just short of statistical significance, namely to the disadvantage of the group without the PRF application. Key words: anterior cruciate ligament, arthroscopy, anatomic ACL reconstruction, magnetic resonance imaging of the graft, platelet-rich fibrin, graft healing, MRI signal intensity of the graft.

PURPOSE OF THE STUDY We present the results of the retrospective study comparing the clinical outcomes of outside-in versus all-inside suture techniques of unstable RAMP lesions (RL) of the medial meniscus in patients with simultaneous ACL lesion with a minimum two-year follow-up. MATERIAL AND METHODS The retrospective evaluation covered two groups of patients who underwent the arthroscopic repair of unstable RL in combination with anterior cruciate ligament reconstruction (ACLR). Group 1 included 42 patients (28 men/24 women). Group 2 consisted of 36 patients (21 men/15 women). In Group 1, RL suture repair using the outside-in technique by posteromedial approach with absorbable PDS suture was performed, while in Group 2 the all-inside technique of RL suture via the standard anteromedial portal was applied using the Fast-Fix system (Smith Nephew, USA). The evaluation was done preoperatively and postoperatively with the mean follow-up of 27.9 months in Group 1 and 30.1 months in Group 2. The patients were assessed using the subjective IKDC score and the side-to-side difference (SSD) in ventral laxity was measured by Genourob (GNRB) laximeter at the applied pressure of 134 N and 250 N. Moreover, the failure rate of RAMP lesion repair, ACL graft, necessity of secondary partial meniscectomy and return to pre-injury level of sport were analysed. RESULTS The median IKDC score increased in Group 1 from 56 points preoperatively to 92 points postoperatively and in Group 2 from 58 points preoperatively to 90 points postoperatively (p>0.05). The median value of SSD in ventral laxity of the knee measured by the GNRB laximeter at the applied pressure of 134 N in Group 1 was 5.6 mm preoperatively and 1.9 mm postoperatively and in Group 2 it was 5.9 mm preoperatively and 2.3 mm postoperatively. At the pressure of 250 N, the median value in Group 1 was 7.9 mm preoperatively and 2.7 mm postoperatively and in Group 2 it was 8.1 mm preoperatively and 3.2 mm postoperatively. When comparing the SSD of the groups postoperatively, no statistically significant difference was found (p>0.05). Revision arthroscopy was performed in 8 patients. In 1 patient (2.4 %) in Group 1 and in 4 patients (11.1%) in Group 2 a rerupture of the RL of the meniscus occurred and partial meniscectomy was performed. In Group 2, statistically significant higher occurrence of the RL suture failure (p<0.05) was reported and there was a need to perform partial medial meniscectomy (p<0.05). The ACL graft failure was observed in 2 patients (4.7%) in Group 1 and in 3 patients (8.3%) in Group 2 (p>0.05). 31 evaluated patients (73.8%) from Group 1 and 24 patients (66.7%) from Group 2 (p>0.05) returned to the pre-injury level of sports activities. DISCUSSION When comparing the outcomes of individual techniques of the RL repair published in recent literature with our conclusions, we may state that the results of subjective as well as objective criteria achieved were similar to those reported by other authors worldwide. No study has so far been published which would compare the outcomes of the by us presented two surgical techniques of the RL suture in an ACL-deficient knee with a minimum follow-up of 24 months. CONCLUSIONS Both the surgical techniques of unstable RL repair in combination with the ACLR using a tendon graft result in a statistically significant improvement of clinical outcomes postoperatively. In Group 2, with the all-inside RL repair, a statistically significant higher failure rate of RL repair was confirmed as well as the need to perform secondary partial meniscectomy compared to Group 1. Key words: RAMP lesion, ACL-deficient knee, unstable medial meniscus lesion, repair of meniscus, all-inside technique, posteromedial technique, ACL reconstruction.

PURPOSE OF THE STUDY Acute knee dislocation is a less common injury of the knee joint. It is, however, a serious injury with a high rate of nerve and vascular damage and it is considered a limb threatening injury with long-term functional disability, which can ultimately lead to amputation. Knee dislocations constitute less than 0.5% of all joint dislocations. Most of these injuries occur in highenergy traumas and careful diagnosis can identify the patient at risk of this injury. MATERIAL AND METHODS The total number of patients with knee dislocation was 37. The incidence of knee dislocation was 2.5 patients per year. The mean age of patients was 49 years. After the evaluation of blood supply to the limb and before the examination of the ligament injury, routine X-ray views of the affected joint were performed. It was necessary to confirm good blood supply of the limb, in which knee dislocation had been suspected. In patients with reduced knee joint and asymmetric pulses in the lower limb, CT angiography was indicated. The absence of peripheral pulses and the presence of serious clinical signs of peripheral blood supply disruption in case of the reduced knee or irreducible knee dislocation necessitated immediate revision by a vascular surgeon performed in the operating room. RESULTS Dislocation of the knee without TKA (a total of 34 cases) was caused by a high-energy trauma in 19 cases (56%) and in 7 cases (21%) it was a part of polytrauma. The most common was a motorcycle accident, namely in 7 cases (21%). In 12 cases (35%), it was a low-energy trauma, a fall or a slip while walking. In three cases (9%), the patients suffered an open knee dislocation. In 18 patients (47%), no knee surgery was performed. The knee ligament injury was treated non-operatively through knee brace fixation. An open revision with sutures of injured ligament structures and knee capsule was performed in 16 patients (42%). In two cases, above-the-knee amputation was done. External fixation was performed in two polytrauma patients. Three cases of infectious complications were reported. Nerve lesions were observed in 9 cases (25%). Vascular lesions were recorded in 9 cases (25%). Deep vein thrombosis was observed in three cases in our study group. The Lysholm knee questionnaire was used to assess subjective difficulties. DISCUSSION In agreement with the literature, these injuries occur most frequently when riding on motorcycle. The patients, in whom a vascular lesion was identified and revascularisation performed within 8 hours, showed a significantly lower incidence of amputations (11%) compared to those who underwent surgery after 8 hours (86%). Majority of vascular surgeons consider 6 hours to be the time limit for the performance of vascular reconstruction since a surgery performed after 6 hours is accompanied by a higher complication rate. Currently, the aim of the final treatment is to perform anatomic suture or reconstruction of knee ligaments and meniscus to achieve a stable, pain-free, functional knee and to prevent any complications. CONCLUSIONS Knee joint dislocation ranks among less common injuries that can be accompanied by a vascular injury in 20% on average and a nerve lesion in 10-40% (around 25% on average). A negative X-ray in spontaneous reduction of knee dislocation can be misleading for proper diagnosis. It is crucial to rule out a vascular injury that might be a limb threatening. In case of a vascular lesion, an early reconstruction of vascular supply is necessary within 6 hours after the injury. The revascularisation performed later is accompanied by a high risk of complications and can ultimately lead to above-the-knee amputation. It is most appropriate to refer such serious injuries to specialised trauma centres that avail of necessary equipment and experience with treating the patients who sustained such complicated orthopaedic injuries. As to the ligament reconstruction, most surgeons prefer to postpone the procedure in majority of cases by 10-14 days. Key words: knee dislocation, vascular injury, neurologic injury, ligament reconstruction, irreducible dislocation.

PURPOSE OF THE STUDY In this randomized prospective study, we monitored and compared perioperative changes in skeletal muscle enzymes blood levels in open and mini-invasive stabilization of thoracolumbar spine fractures. The established hypothesis was to confirm higher blood levels of muscle enzymes in open stabilization. MATERIAL AND METHODS This study included 38 patients with the mean age of 46.4 years. 19 injuries were managed in an open procedure and 19 procedures were mini-invasive. Venous blood was taken intermittently at short intervals to determine the levels of skeletal muscle enzymes. The catalytic concentration of creatine kinase was determined via an enzymatic UV-test, and the concentration of myoglobin via electro-chemiluminescent immunoassay. Enzyme levels were processed statistically. The Wilcoxon test was used. RESULTS The median increase in the values of both enzymes is higher in the mini-invasive method than in the open method in both the surgery phase for the injury and in the extraction phase. The median increase in the values of both enzymes is higher in both methods for the primary procedure phase compared to the extraction phase. All results are statistically significant at p of <0.05. All tests were calculated using the MATLAB Statistics Toolbox. DISCUSSION A very surprising finding, when testing the hypothesis of the levels increasing mainly in open stabilization, was confirming the opposite. Both enzymes were higher in the mini-invasive approach to stabilising the spine after the injury, but also after the extraction. This contradicts the available literature. However, this can be explained by the methodology of enzyme levels determination in the previously published studies. We believe that this phenomenon can be partially caused by an iatrogenic mini-compartment of muscles in the postoperative period, absence of wound drainage, but also by higher muscle contusion when inserting bolts through the tubes via small incisions, when the tubes penetrate to the entry points relatively violently and the muscles in this area are affected more than in the classical skeletization. CONCLUSIONS Analysis of biochemical changes in open and mini-invasive surgery did not confirm the hypothesis that levels of creatine kinase and myoglobin enzymes increase especially in open stabilization. On the contrary, they were statistically significantly higher in mini-invasive procedures. Key words: creatine kinase, myoglobin, muscle enzymes, spine fracture, spine surgery, miniinvasive surgery.

PURPOSE OF THE STUDY Periprosthetic distal femoral fractures (PDFF) constitute an unpleasant complication in patients with a total knee replacement (TKR). The incidence reported in literature is 0.3-2.5 %. The number of periprosthetic knee fractures has been increasing due to the ageing of population, a growing number of implants, a longer life expectancy of patients, a more intensive physical activity of patients, and osteoporosis. Most of these fractures are treated surgically, non-surgical treatment is reserved solely for patients unable to undergo a surgery for general health conditions. MATERIAL AND METHODS Our retrospective study evaluated the group of patients with PDFF who were treated at out department in the period 2007- 2016 and 2,975 primary TKR were performed. The total number of patients with PDFF was 56. The mean age of patients with PDFF was 77 years (56-94 years) and at the time of fracture the mean age was 71 years in men and 78 years in women. The average time from the TKR to periprosthetic fracture was 8.2 years (0-20 years). The fractures were assessed using the Su classification modified by Krbec. RESULTS A primary TKR was performed in 46 cases for gonarthrosis, in 6 cases for rheumatoid arthritis and in 4 cases for secondary, post-traumatic gonarthrosis. The average incidence of periprosthetic distal femoral fractures was 5-6 cases per year. Women represented 86 %, men 14 %. Su Type I fracture was diagnosed in 25 % of cases, Su Type II fractures in 71 %, and Su Type III fractures 4 %. 52 patients with PDFF were treated surgically, in 4 cases conservative treatment was opted for. The average treatment time of PDFF to healing by callus formation was 6.6 months (3-12 months). Mortality during the first 3 months after osteosynthesis of PDFF was 9 %. A failure of osteosynthesis of PDFF was reported in 4 cases. DISCUSSION Multiple classification systems were developed to assess these fractures. The most appropriate we consider the classification of Su et al. classifying the PDFF into 3 groups, namely based on the height of the fracture line relative to the femoral component. Osteosynthesis by retrograde femoral nail is indicated for periprosthetic fractures, with sufficient bone mass in distal femur, which allows stable distal fixation. The new generation of anatomically shaped angular stable implants gives us yet another option for osteosynthesis of PDFF. Many studies point at the advantages of these implants in osteoporotic bone as against the conventional plates. CONCLUSIONS The number of PDFF has been increasing. The main methods of internal osteosynthesis continue to be the angular stable plates and the retrograde femoral nail. Preoperative planning is important to determine the type and dimensions of the existing femoral component and to distinguish whether or not it has come loose. The choice of the implant may depend on the bone mass available for distal fixation. The retrograde femoral nail is usually the most suitable method of treatment for proximal PDFF (Su Type I). The angular stable plates can be used for PDFF originating at the femoral component (Su Type II and Type III). Very distal fractures classified as Su Type III with a loose femoral component require a revision surgery with a TKR with stems. The surgeon should be prepared for a revision surgery if the intraoperative finding is more complicated than anticipated based on the preoperative radiograph. Key words:total knee arthroplasty, periprosthetic fracture, osteosynthesis.

PURPOSE OF THE STUDY The retrospective study aims to compare the outcomes of augmentation of neutral triangle formed after the calcaneal fracture reduction with osteosynthesis using the locking compression plate with the outcomes of osteosynthesis without augmentation. MATERIAL AND METHODS In the period from 2005 to January 2011, 98 patients with 114 calcaneal fractures were treated by open reduction and internal fixation (ORIF) method with the use of calcaneal plate. The group included 15 women (15.3%) and 83 men (84.7%), with the mean age of 39.2 years (12-62 years). There were 16 cases of bilateral calcaneal fractures, of which 2 in women (12.5%) and 14 in men (87.5%). The fractures were classified based on the Sanders classification as Type I -IV. The patients with Type II and III fracture according to the Sanders classification were indicated for surgical treatment with ORIF using the calcaneal LCP. The defect in the region of neutral triangle of the calcaneus was filled with the injectable hydroxyapatite cement. The cohort of operated patients was evaluated based on the AOFAS (American Orthopaedic Foot and Ankle Society) Clinical Rating System. The bilateral fractures were not evaluated. This group shows a substantially higher occurrence of associated injuries, which causes strong distortion of results. RESULTS The cohort of 82 operated patients with Sanders Type II and III fractures were evaluated. In 20 fractures (24.4%) the defect in the calcaneus body was filled with hydroxyapatite cement. In osteosynthesis without defect augmentation an excellent result was achieved in 21 patients (33.9%). A good result was reported in 24 patients (38.7%), a satisfactory result in 12 patients (19.4%) and a poor result in 5 patients (8.0%). In patients with osteosynthesis of the calcaneus with augmentation, an excellent result was achieved in 6 cases (30%), a good result in 5 cases (25%), a satisfactory result in 7 cases (35%) and a poor result in 2 cases (10%). Early postoperative complications were observed in a total of 13 patients (15.8%). In osteosynthesis without defect augmentation, there were 2 cases of wound dehiscence (3.2%), 3 cases of marginal skin necrosis (4.8%), 4 cases of superficial wound infection (6.4%) and 1 case of deep wound infection (1.6%). In patients with performed augmentation, wound dehiscence was seen in 1 case (5%), superficial wound infection in 1 case (5%) and superficial marginal skin necrosis in 1 case (5%). Deep wound infection was not reported in this group. DISCUSSION A question frequently discussed is the filling of defect in the diaphysis of calcaneus. Brodt et al. state a statistically higher stability of the calcaneus in osteosynthesis with augmentation, but he does not use the locking plate. Longino in his study compares the results of calcaneal osteosynthesis with spongioplasty with a graft from pelvis and without it and does not observe any major differences in the final outcome in his cohort. Elsner evaluates the results in 18 patients, in whom calcium phosphate cement augmentation was used for osteosynthesis. Over the period of three years he did not observe a higher rate of complications. Schildhauer assesses the early load of the calcaneus with tricalcium phosphate cement augmentation. After three weeks of full loading no loss of reduction was found. Thordarson evaluates 11 operated patients with Sanders type II and III calcaneal fracture. The defect of the calcaneus was filled by calcium phosphate cement. In this small group 1 case of serious infection complication and 1 loss of reduction with full load at six weeks after the surgery were observed. In our group no differences were observed between the outcomes of patients with performed or not performed defect augmentation in the neutral triangle site. A higher percentage of complications in patients with filled defect of the calcaneus was not observed either. CONCLUSIONS The operative treatment of displaced intra-articular fractures consisting of open reduction from extended lateral approach and internal calcaneal LCP fixation brings good results. We concluded that there is no statistically significant difference in the results of osteosynthesis with a locking plate alone and combined with augmentation of diaphyseal defect of the calcaneus. Filling of the diaphyseal defect in the calcaneus is not necessary, it neither accelerates the healing, nor brings better treatment outcomes Key words: calcaneal fracture, cement augmentation of defect, locking plate, extended lateral approach.

PURPOSE OF THE STUDY This original paper aims to present the conclusions of the prospective study evaluating the clinical results of anatomical all-inside ACL reconstruction using quadrupled semitendinosustendon graft with posteromedial harvest using suspensory fixation by Tightrope implants at the follow-up of at least 12 months. MATERIAL AND METHODS The prospective study included a total of 119 patients (74 men/39 women) with the mean age of 28.3 (18-52) years, in whom demographic data was collected and a clinical examination was performed. The patients satisfying the "inclusion" and "exclusion" criteria were enrolled in the study and subsequently underwent the same, aforementioned surgical procedure performed by a single surgeon. Preoperatively and at a minimum 12-month follow-up the following subjective criteria were evaluated using the Lysholm and IKDC subjective scores and the Visual Analogue Scale (VAS) (0-10). The objective parameters comprised the side-to-side difference in anterior knee laxity assessed by Genourob arthrometer with an applied pressure of 134 and 250 N, anterior drawer test, and the pivot shift test. The occurrence of graft failure, complications and return to pre-injury sport levels were monitored. The obtained data was statistically evaluated at the statistical significance level of 0.05. RESULTS A total of 89 patients were assessed at the follow-up of at least 12 months after the surgery. The median Lysholm score increased over time from 58.7 preoperatively to 94.2 postoperatively (p < 0.05) and the IKDC subjective score went up from 46.3 to 91.4 (p < 0.05). The median postoperative VAS kept decreasing from 7.3 (Day 2), 5.1 (Day 14), 3.1 (Week 6), 1.2 (Month 6) to 0.3 at 12 months after the surgical procedure. Preoperatively, the results were significantly positive (i.e. C, D) in 52.8% (C) and 21.4% (D), whereas postoperatively the results of the PST were significantly positive only in 4%. Therefore, the surgical procedure was conducive to a statistically significant decrease in rotational knee laxity over time (p < 0.05). The median side-to-side difference in anterior laxity of the operated knee objectively assessed by GNRB arthrometer with the applied pressure of 134 N was 4.2 mm (3.1-6.8) as against the postoperative 1.2 mm (0.4-2.1) and with the applied pressure of 250 N it was 6.2 mm (4.6-8.7) prior to the surgical procedure versus 2.4 mm (1.6-3.5) postoperatively. That concerned a statistically significant decrease of postoperative side-to-side difference in anterior laxity of the operated knee at both the measured pressures (p < 0.05). The graft failed in 3 patients only (3.4%), no major complications associated with the surgical procedure were observed and 62 of the evaluated patients (69.6%) were able to return to the pre-injury level of sport within one year after the surgery. DISCUSSION When comparing the results obtained by our study with the conclusions of clinical studies carried out by other authors and evaluating similar clinical parameters with the identical surgical technique applied, it is obvious that in our group of patients we achieved similar clinical results as the other authors from abroad. CONCLUSIONS The results of our study showed that the all-inside ACL anatomical reconstruction using quadrupled semitendinosus tendon graft with posteromedial harvest with suspensory fixation by Tightrope implants at one year after the surgery bring very good subjective as well as objective clinical results and minimum complications. Key words:anterior cruciate ligament tear, anatomical ACL reconstruction, all-inside technique, posteromedial harvest, quadrupled semitendinosustendon graft, retrograde drilling, suspensory graft fixation.

PURPOSE OF THE STUDY The aim of our prospective study was to establish correlation between the arthro-MRI and arthroscopic findings in patients active in sports clinically suspected of having a hip labral tear. We sought to identify the benefits of arthro-MRI for clinical practice prior to the considered hip arthroscopy. MATERIAL AND METHODS The prospective study included 34 patients with hip pain and clinically suspected of having a labral tear. The group consisted of 19 men (55.9%) and 15 women (44.1%) of the mean age of 32.2 years (18 to 50 years). All our patients were active athletes, either professional (12; 35.3%) or recreational (22; 64.7%). Included in the study were exclusively patients aged 18-50 with hip pain lasting longer than 3 months, not responding to conservative therapy, with normal X-ray findings, or FAI syndrome. The patients underwent arthro-MRI and subsequently also hip arthroscopy, namely within no more than 3 months. The description of findings was translated into simple numerical scales, assessed using Spearman s rank correlation coefficient. We also examined the specificity, sensitivity, positive and negative predictive values and the odds ratio at various cut-off values of the scale for arthro-MRI. The statistical significance was set at the alpha level = 5%. The quality of tests was also evaluated using the ROC curve. RESULTS In hips assessed by the radiologist as reliably with no pathological finding (MRI type 1) the negative predictive value achieves 83.3% and the positive predictive value of 85.7%, with 96.0% sensitivity and 55.6% specificity. When evaluating the reliably negative finding together with the likely negative finding (MRI type 2) as against the pathological and certainly pathological findings (MRI type 3 and 4), the negative predictive value is 57.1%, the positive predictive value 95.0%, the specificity 88.9% and the sensitivity 76.0%. DISCUSSION In our study, the values achieved were comparable to or better than those reported by foreign authors in their studies establishing correlations between the arthro-MRI and intraoperative findings. Significantly higher was primarily the negative predictive value. CONCLUSIONS The results of our study indicate that the arthro-MRI performed as a part of preoperative examination prior to hip arthroscopy has adequate specificity and sensitivity in patients with suspected labral tear. Based on this examination a decision can be made as to whether to perform arthroscopy. Our study also shows that it is essential to have a highly competent radiologist to evaluate the arthro-MRI results. Key words: hip arthroscopy, labral tears, arthro-MRI, hip joint, predictive value of tests, sensitivity and specificity, minimally invasive surgical procedures/methods.

PURPOSE OF THE STUDY This retrospective study aims to present short-term clinical outcomes of endoscopic treatment of patients with greater trochanteric pain syndrome (GTPS). MATERIAL AND METHODS The evaluated study population was composed of a total of 19 patients (16 women, 3 men) with the mean age of 47 years (19-63 years). In twelve cases the right hip joint was affected, in the remaining seven cases it was the left side. The retrospective evaluation was carried out only in patients with greater trochanteric pain syndrome caused by independent chronic trochanteric bursitis without the presence of m. gluteus medius tear not responding to at least 3 months of conservative treatment. In patients from the followed-up study population, endoscopic trochanteric bursectomy was performed alone or in combination with iliotibial band release. The clinical results were evaluated preoperatively and with a minimum follow-up period of 1 year after the surgery (mean 16 months). The Visual Analogue Scale (VAS) for assessment of pain and WOMAC (Western Ontario MacMaster) score were used. In both the evaluated criteria (VAS and WOMAC score) preoperative and postoperative results were compared. Moreover, duration of surgery and presence of postoperative complications were assessed. Statistical evaluation of clinical results was carried out by an independent statistician. In order to compare the parameter of WOMAC score and VAS pre- and post-operatively the Mann-Whitney Exact Test was used. The statistical significance was set at 0.05. RESULTS The preoperative VAS score ranged 5-9 (mean 7.6) and the postoperative VAS ranged 0-5 (mean 2.3). The WOMAC score ranged 56.3-69.7 (mean 64.2) preoperatively and 79.8-98.3 (mean 89.7) postoperatively. When both the evaluated parameters of VAS and WOMAC score were compared in time, a statistically significant improvement (p<0.05) was achieved postoperatively. The mean duration of surgical procedure was 68 minutes. Moreover, in peritrochanteric space apart from chronic bursitis also another pathology was found in a total of 14 cases (74%). In six cases (32%) it was a mild degeneration of m. gluteus medius (treated only with debridement) and in eight patients who underwent surgery (42%) the dorsal third of tractus iliotibialis was hypertrophic and protruding into bursa (treated with an incision of the hypertrophied part of the band). No serious neurovascular or thromboembolic complications were recorded. Only minor postoperative complications in a total of 7 patients who underwent surgery (37%) occurred. DISCUSSION There are lots of studies in literature presenting the results of endoscopic treatment of GTPS either using an independent trochanteric bursectomy or its combination with iliotibial band release. In our study we succeeded in achieving similar clinical results as those achieved by the other authors engaged in this area. CONCLUSIONS It has been proven in this retrospective study that the technique of endoscopic trochanteric bursectomy in patients with greater trochanteric pain syndrome yields statistically significant improvement of clinical results with the concurrent minimum incidence of postoperative complications. Key words: greater trochanteric pain syndrome, peritrochanteric space, recalcitrant trochanteric bursitis, hip arthroscopy, endoscopic trochanteric bursectomy, iliotibial band release.
